Hey Manu,

Agreed. Oftentimes people want to put up just a few answer choices, none of which are correct, to try to get a sense of which is "best". This is not a good idea. I don't personally like either of these examples:

By showing that South Africa does not have a free market and in in fact a kind of collectivist welfare state for whites only, Sowell argues that American conservatives have no valid ideological grounds to be in sympathy with the Pretoria regime.

a.
b. to sympathize with
c. for sympathizing with

Both "grounds to" and "grounds for" are correct idioms, so I'm not sure what case you can make for one over the other. I looked it up, and they are both legal. I don't buy this question, so let's ignore it.

-t

Hey Manu,

Thanks for that. I know the official answer is (C), but my understanding of idioms is that both (B) and (C) are justifiable, so I don't think this is realistic.

These are adequate grounds for divorce.
He said these are grounds to initiate a separation.

Both of those sentences are okay.

-t

Hey Aditya,

No, this is a separate idiom: "grounds to". So it isn't about intent.

-t

Hey Sana,

Again, "to" is not being used for intention here. It's an idiom, much like:

He is thought to be a great man.
He is known to be a great golfer.
He admits to being a terrible person.

-t

Exactly right, Aditya!
